I'm particularly interested in nonlinear physics, quantum mechanics, relativity (Jorrie is the local CR4 expert, do yourself a favor and read his blog), and the standard model (quarks, etc.).
I'm afraid my work in applied quantum mechanics has opened my eyes to the fact that genetics in the end is nothing more than extremely complicated chemical reactions.
